Abstract (en)
The present invention provides a method for establishing a secure communication channel between a client (C) and a remote server (S), said client (C) and remote server (S) exchanging data through an intermediate entity (G), said client (C) having a long-term key pair (sk c ,pk c ), said remote server generating an ephemeral key (sk s ,pk s ), the method comprising a mutual authentication step wherein the client (C) sends a public key (pk c ) of said long-term key pair (sk c ,pk c ) and the proof that said public key (pk c ) is valid to the server (S), and wherein the remote server (S) sends the public key (pk s ) of said ephemeral key pair (sk s ,pk s ) to the client (C). The client (C) generates an ephemeral key pair (sk cc ,pk cc ) and sends the public key (pk cc ) of said ephemeral key pair (sk cc ,pk cc ) to the server (S) so as to generate a secret common to the client (C) and to the remote server (S) for opening the secure communication channel.
